The goal of the study was to teach farmers and breeders how to turn cow manure into organic fertilizer through composting, to improve sandy soil conditions in a specific area. The researchers used a method called laminated heap composting, mixing cow dung with straw to reach the ideal carbon-nitrogen ratio. After 9 weeks of composting, the cow dung transformed into black, odorless compost with a crumbly texture, reducing its weight by 40-45%. This process helps manage livestock waste, creates healthier organic fertilizer, and enhances the quality of sandy soil.
